Application filed February 24, 1915. Serial No. 10,820.

- at the same time provide for maintaining the insulation in its proper position within'the shell.

7 With these objects in view my invention consists in the novel features of construction hereinafter fully described and pointed out 'in the claim.

In the drawings forming a part of this specification, Figure 1, is an elevation of a socket shell constructed in accordance with my invention. Fig. 2 is a vertical sectional.

view of the same and, Fig. 3 is an enlarged sectional view of the cap with the insulation arranged therein.

In the practical embodiment of my invention I employ a cap portion A, a body portion B, and aring portion C, these parts constituting when connected a shell, for the incandescent lamp socket D, shown in dotted lines in Fig. 2.

The cap A has an interior lining of fiber insulation E held in place in a manner hereinafter explained and the bod portion B also has an insulation lining ,which extends from the top to the bottomof the same.

7 While I have shown my invention as apsocket it is ObVlOllS that I t can be employs equally as well in conneclied to a side ke ,ing the fiber insulation E in place.

- tion with a keyless socket, or one of the pullchain type.

The lower end of the cap A fits into'the upper end of the body B, and in order to unite these parts the depending flanged portion 0, of the ring is threaded and adapted. to engage the threads B, produced upon the upper end of the body B. The upper portion 0 of the ring engages the shouldered portion of the cap, and the inner edge of this portion C engages an annular groove which is produced in the cap by making said cap with an annular interior seat or reentrant portion A, which serves as a seat for hold- This portion A of the cap A therefore serves the double function of maintaining the fiber insulation in its proper position in the interior of the shell, and providing the positioning means for the clamping ring upon the exterior of shell.

It will be understood that the cap is lined with its insulation and the body provided with its lining, and then the cap and body portions are-connected together by screwing the ring upon the upper end of the body portion drawlng the two parts together and pro-v viding the complete socket shell. What I claim is; A socket shell comprising a cap having an annular reentrant portion adapted to provide a seat for fiber insulation, a body portion into which the lower end of the cap fits and a clamping ring adapted to connect the cap and body portions together.
